2. Description of Related Arts

An auxiliary shelter frame is widely used today for mounting on aprimary spectacle frame, especially an auxiliary shelter frame withmagnetic attachment is even commonly used in recent market. Theadvantage of the magnetic shelter frame is that when the shelter frameis placed in front of the primary spectacle frame, due to the magneticattraction, the shelter frame will be automatically guided and attractedby the primary spectacle frame having magnet embedded thereon, so as tosecurely mount the shelter frame in front of the primary spectacleframe. Thus, the wearer can easily use one hand to attach or detach theshelter frame during exercising or driving.

However, even though the shelter frame can be detached easily from theprimary spectacle frame, the wearer cannot take out the shelter frame insuch a quick response especially when the wearer has to switch theshelter frame back and forth on the primary spectacle. For example, whenthe wearing is driving through a tunnel, the wearer may need to detachthe shelter frame when entering the tunnel and attach the shelter frameback on the primary spectacle frame after exiting the tunnel. Thedetaching and attaching operation of the shelter frame on the primaryspectacle frame will give trouble to the wearer because the wearer maypay more attention on the operation of the shelter frame rather than onthe road, which is dangerous while driving. Beside the drivers, it isalso inconvenient for many wearers such as golf prayers and baseballplayers having outdoor activities, who have to switch the shelter frameback and forth on the primary spectacle frame.

Moreover, since the primary spectacle frame comprises magnets embeddedthereon, which will increase the weight of the primary spectacle frame,such that the wearer may feel uncomfortable because of the additionalweight of the primary spectacle frame even though the shelter frame isdetached therefrom. Moreover, it is known that the magnets producemagnetic field which may affect the blood circulation of a human being.When the wearer always wear the primary spectacle frame having themagnets embedded thereon, the magnetic field produced by those magnetsmay cause eye infection or even serious headache for the wear.

Thus, the magnets embedded on the primary spectacle frame may not onlyadversely affect the entire ornamental appearance of the primaryspectacle frame but also limit the designers to create and design newstyle of the frames in the fashion market.
